MACHINE-FOR J APANNING SMALL ARTICLES.

SPECIFICATION forming part of Letters Patent No. 7 28,606, dated May' 19, 1903.

Application filed :l'uly 31. 1902.

To all whom, it may. concern:

Be it known that I, THOMAS A. PERRINS, a citizen of the United States, residing at Seymour, county of'New Haven, State of Connecticut, have invented a new and useful Machine for Japanning Small Articles, of which the following is a specification.

My invention relates to the class of machines for japanning eyelets and other small articles illustrated and described in Letters Patent No. 701,386, granted tome June 3, 1902, and has for its object to provide means for applying japan to the portion of the articles to be covered mechanically and without waste, so that I am enabled to give to the articles a dip finish instead of a brush finish andto efiect a great saving in labor, as well as in material, for the reason that the painting over of the eyelets with brushes is dispensed with, likewise all mechanism for washing and .cleaning the carrying-belt, all the japan used being placed upon the eyelets, so that the belt remains practically clean, my improved machine enabling me to produce, in brief, better-finished eyelets at greatly-reduced cost both in labor and material. In order to accomplish the desired result, I have devised the novel mechanism for applying the japan, which I will now describe, referring to the accompanying drawings, forming part of this specification, and using reference characters to designate the several parts.

Figure 1 is a plan View illustrating one form of my novel japanning-roller and the trough detached; Fig. 2, a side elevation correspondingtherewith; Fig. 3, a crosssection of the machine, showing the japanning-roller and the holding-levers in elevation; Fig. 4, alongitudinalsection of the ja'panning-roller on an enlarged scale; Fig. 5, an end elevation of the japanning-roller, the end disk being partly broken awayto show one of the non-rotating retainers; Fig. 6, a plan view of one end of the machine, showing the endless carrying-belt and the pulley by which it is carried; Fig. 7, a sect-ionon the line 7 7 in Figs. 1 and 3; Fig. 8, a detail plan view of a portion of the frame, showing a variant form of japanning-roller in horizontal section on the line 8 8 in Fig. 9; Fig. 9, a section on the line 9 9 in Fig. 8; Fig. 10, a View similar to Fig. 8, illustrating still another form of ja- Serial No. 117,792. (No model.)

panning-roller in horizontal section on the line 10 10 in Fig. 11; and Fig.1l is a section on the line 11 11 in Fig. 10.

A denotes an endless metallic carrying-belt having holes or perforations 10 to adapt it to receive small articles, as eyelets, and B a pulley over which one end of the belt passes. Pulley B is shown as carried by a shaft 11, journaled in suitable bearings 12 and having at one end a pulley 13, over which a belt (not shown) passes to drive the pulley and the belt. At the other end of shaft 11 is a smaller belt-pulley 14, the function of which will presently be explained.

The essential feature of my present invention is a japanning-ro'ller C, provided with non-rotating retainers l5,which act to prevent articles that are being carried by the carrying-belt from adhering to the japanningroller and being drawn out of the belt. This roller is carried by a shaft 16, suitably journaled in the framework of the machine, which as a whole I have designated by D. At one end of shaft 16 is a belt-pulley 17, which corresponds with belt-pulley 14 on shaft 11. A belt (not shown) passing over these pulleys imparts motion to the japanning-roller, the pulleys being so proportioned as to give to the japanning-roller a surface speed just equal to the speed at which the carrying-belt moves.

In FigsAand 5 I have specifically illustrated a form of japa'nning-roller consisting of a series of disks 18, which are provided with small hubs 19, so that when the disks are secured together, as by bolts 23, a compound roller is formed having grooves 38 between the disks to receive the retainers 15. In this form the retainers consist of plates having central openings2l to receive the hubs and extensions 22, which act to retain the articles in the carrying-belt in place as the belt passes along, as will be more fully explained. These retainers are made very thinfor example, ten onethousandths of an inch in thicknessthe exact thickness in thousandths of an inch being of course unimportant. The roller is in practice rigidly secured to shaft 16, which receives motion in the manner already described. It should be noted that the hubs 19 turn freely within openings 21 in the retainers and that the retainers are held against ISO being carried around with the disks by a crosspiece 24, which extends across the machine from side to side of the framework just above the retainers.

In the form of japanning-roller illustrated in Figs. 8 and 9 the roller may be asolid cylinder and the grooves 38 to receive the retainers may be cut therein- In this form the retainers, which I have indicated by 15, may be strips of flattened wire bent around in the grooves and having extensions 22 to retain the articles in the belt and a cross-piece 24 to hold the retainers against being carried around by the roller, the same as in the other form.

In the form of japanning-roller illustrated in Figs. 10 and 11 the roller may be a solid cylinder with grooves 38 out therein, the same as in Figs. 8 and 9; but in this form the retainers, which I have indicated by 15 are not carried by the roller, but are rigidly secured in any suitable or convenient manner between the side pieces of the framework. Retainers 15 are plates and may be the same thickness as retainers 15 in Figs. 1 to 7, inclusive. The forward edges of these plates are concave curves just corresponding with the convexity of the bottoms of grooves 38, and the grooves are made just wide enough to receive the retainers freely, so that in use they will engage the bottoms of the grooves and will operate to retain the articles in the carrying-belt precisely as in the other forms. I have shown the retainers as alternating with blocks 39, by which they are spaced, and the retainers and blocks as locked in place by a bolt 40, extending through retainers, blocks, and the side pieces of the framework.

E denotes the japan-trough, one side of which is formed byjapanning-rollcr C and the other side, the bottom, and the ends of which consist of a casting F. The ends of this casting are specifically indicated by 25 and are provided with elongated openings 26, (see dotted lines, Fig. (3,) through which shaft 16 passes. The portion of casting F which constitutes one side and the bottom of japantrough E is specificallyindicated by 27. The outer side of casting F is supported by bolts 28, whichpass through elongated openings in the framework and engage the casting. It will be seen from the arrow in Fig. 7 that the motion of the roller is downward from right to left and that an opening or space (indicated by 29) is left between the edge of casting Fand the japanning-roller, through which japan passes. The casting is adjustable toward or from the roller to increase or diminish the size of this opening or space by means of threaded rods 30, which pass through brackets 31 upon casting F and are rigidly securedin theframework, set-nuts 32 being provided on each side of the bracket to lock the casting in place after adjustment. It is necessary in practice that opening or space 29 be made large enough to permit sufficient japan to pass to cover the heads of the articles.

Should more than enough pass, however, theie will be no waste, as it will adhere to the roller and pass back into the trough again. It will be readily understood from Fig. 7 that the eyelets or other articles receive japan from the japanning-roller as they pass under it. In order to insure that each article carried by the belt will be perfectly japanned upon its upper surface, I provide a double series of interlocking holding-levers 33. These levers, which are in form bell-crank levers, are pivoted upon rods 34, extending across the machine from side to side, and their heads or operative ends 35, which lie side by side, are retained in operative position and caused to hold the eyelets or other articles to be japanned which are being carried by the belt up against the japanning-roller by means of springs 36, attached to the other angles of the levers and to a central cross-rod 37, extending across from the opposite sides of the framework.

The operation will be readily understood from the drawings. The manner in which the articles to be japanned are placed in the perforations in the carrying-belt or how they are removed from the belt or how the articles are baked while being carried by the belt are matters of no importance so far as my present invention is concerned. The articles carried by the belt pass under the japanning-roller, as will be clearly understood from Figs. 2, 6, and 7, and their upper surfaces receive japan from the roller. The heads or operative ends of the holding-levers act to retain the articles carried by the belt upward in position to receive japan from the japanningrollerthat is, they prevent the possibility of the carryingbelt sagging and leaving the articles out of contact with the roller and insure that the upper surface of each article shall come in contact with the roller and be japanned thereby. The action of the retainers is to prevent the eyelets or other articles after being japanned from adhering to the japanning-roller and being drawn out of the carryingbelt. As already explained, the roller turns within the retainers, which are themselves locked, against rotation. The retainers are so spaced as to correspond with the rows of eyelets or other articles carried by the belt, a retainer passing over the center of each article and through the coating of japan thereon. The retainers are so thin, however, that the japan instantly fills the lines made by them as soon as the articles have passed, leaving the uppersurface of the articles smoothly and evenly japanned and wholly free from the brush-marks that are unavoidable when japan is applied by means of a brush and also leaving the surface of the belt perfectly clean. In practice the articles only (not the belt) receive japan from the japanning-roller, which is impossible Where japan is applied by means of brushes, in which event more japan is usually placed upon the belt than upon the articles them- IIO selves, causing much waste of japan and loss of time in cleaning the carrying-belt.
